"Hardening" is the process of protecting a system and its applications against unknown threats. And Hardening Linux will explain the main steps that any Network or Systems Administrator needs to take, to protect his computers that run on Linux. This book discusses security of mail servers, web servers, and file servers, as well as hardening IP tables and remote access functionality.

Written in a similar manner to Hardening Windows and Hardening Apache, complete with checklists and reference-style chapters, Hardeing Linux shows Apress’ commitment to publishing books that appeal to the security professional.
